Symbol probe revealed ixformer::infer namespace does NOT exist in base image.
That namespace is xllm's own compiled wrapper layer.
Actual available symbols in base image:
_ixformer_torch.so: silu_and_mul_forward, rms_norm_forward,
fused_add_rms_norm_forward, ixformer_linear, ixformer_linear_ex
libixformer.so: ixinfer_flash_attn_unpad_fwd (different signature)
MoE functions (topk_softmax, group_gemm, moe_expand_input, etc.)
are NOT in any base image .so — MoE must use Python path.
Bridge now only wraps: silu_and_mul, rms_norm, fused_add_rms_norm, linear
These accelerate the per-layer ops that run 200x per token.
- ix_bridge.py: auto-discover ixformer .so files, pass as extra_ldflags
- ix_moe_bridge.cpp: fix mangled header from bad sed, add #include <optional>
- verify_single_gpu.py: also pass extra_ldflags during JIT compile
The undefined symbol _ZN8ixformer5infer12silu_and_mulERN2at6TensorES3_
lives in libixformer.so — need to explicitly link it.
